2013-12-02Using local variable for token_cache.Dmitry Kovalev
The difference with the old code is that originally the whole token_cache was initialized with zeros at the beginning of decode_coefs() function. Now we set several zero values explicitly with "token_cache[scan[c]] = 0". Change-Id: I88cc5031f01d13012d1a4491739c36cb44f9401e
2013-11-13Simplifies band-getting with a static arrayDeb Mukherjee
Simplifies the code by implementing band mapping with static arrays. A lot of the code complexity introduced in a previous patch disappears. Change-Id: Ia3fac36e594fb5ad2d55ae141c58bba4c55c2d28
2013-11-12Calculating transform block offsets (x and y) only once.Dmitry Kovalev
Change-Id: I4b5106bdc08fd4551339b968c13428a8f43122e2
2013-11-12Removes conditional statements from band gettingDeb Mukherjee
Implements scan order to band map with arrays in both the encoder and decoder to remove conditional statements. Encoding seems to be about 1% faster at speed 0, tested on football. Decoding seems to be about 0.5-1% faster on a set of 25 videos. Change-Id: Idb233ca0b9e0efd790e30880642e8717e1c5c8dd
2013-11-05token_cache changes in decoderDeb Mukherjee
Removes stack-alocation of token_cache in decode_coefs function Seems to achieve about 1% decode speed improvement as tested on 25 480p videos. Change-Id: I8e7eb3361fa09d9654dfad0677a6d606701fdc6e
2013-10-31Reducing the number of foreach_transformed_block() calls.Dmitry Kovalev
The change doesn't affect the bitstream. It changes the order or function calls and affects how we reconstruct intra- and inter-blocks. Speed up is about 1...1.5%. For intra-blocks: Before: for each transform block read tokens for each transform block do prediction for each transform block do inverse transform Now: for each transform block read tokens do prediction do inverse transform For inter-blocks: Before: for each transform block read tokens for each transform block do inverse transform Now: for each transform block read tokens do inverse transform Change-Id: I12a79bf1aa5a18c351b8010369bd3ff1deae1570
2013-10-21vp9_decode_tokens: limit scope of function paramsJames Zern
replace VP9D_COMP usage with the (slightly) more targeted VP9_COMMON/MACROBLCKD/struct segmentation structures. Change-Id: Iabb3616e231417b0e17b7e4b384ea63167a81745
2013-08-26Renaming BLOCK_SIZE_TYPE to BLOCK_SIZE in the common/decoder.Dmitry Kovalev
Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away after encoder's patch. Change-Id: I06ec6a6f079401439843ec981d1496234fd7775c
2013-07-25General cleanups.Dmitry Kovalev
Removing unused constants, macros, and function declarations. Using ROUND_POWER_OF_TWO macro, vp9_zero, vp9_copy where possible. Moving #include from *.h to *.c. Merging for loops for motion vectors. Change-Id: Ic3bf841764a2bb177128bb3a6d7aa8f68229cd13

2013-05-07Deprecate the newbintramode experiment.Paul Wilkins
Clean out code relating to newbintramode. Change-Id: Ie91f4f156cdf60ce0da8ca407c1c9cb00c7d0705
2013-04-25Fix incorrect dequant used in detokenizeJohn Koleszar
The quantizer can vary per-plane, and the dequantization vector is available in the per-plane part of MACROBLOCKD. The previous code would incorrectly use the Y quantizer for the whole macroblock. Change-Id: I3ab418aef9168ea0ddcfa4b7c0be32ae48b536d7
2013-04-22Moved dequantization into the token decoderScott LaVarnway
Mostly for cleanup purposes. Now we should be able to rework the encoder/decoder to use a common idct/add function. Change-Id: I1597cc59812f362ecec0a3493b6101a6cc6fa7ff
2013-04-18Replacing BOOLEAN_DECODER with vp9_reader inside vp9_detokenize.Dmitry Kovalev
Change-Id: I71369a30a86111ae737168c795a29b4d8cff6ebf
2013-04-10Make SB Decoding units size-independentJingning Han
Unify the sb32x32 and sb64x64 decoding units, which also allow for other rectangular block sizes. Change-Id: Ia5187ab2af56f98c3f99272bdf4dbcabe798ad5d
2013-04-04Fixing the newbintramodes experimentDeb Mukherjee
Adds back special casing B_PRED mode decoding but protected within the experimental macro. Change-Id: If98dc8e56b0ecfb1202540c2b7dfdd070cb81ca0
2013-04-03Remove special case vp9_decode_coefs_4x4John Koleszar
This code was only called in the BPRED case, but had no real special case associated with it. Made BPRED behave like all other modes. No bitstream change. Change-Id: I87ba11fe723928b6314d094979011228d5ba006f
2013-03-04Make superblocks independent of macroblock code and data.Ronald S. Bultje
Split macroblock and superblock tokenization and detokenization functions and coefficient-related data structs so that the bitstream layout and related code of superblock coefficients looks less like it's a hack to fit macroblocks in superblocks. In addition, unify chroma transform size selection from luma transform size (i.e. always use the same size, as long as it fits the predictor); in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma transform will now use the 16x16 (instead of the 8x8) chroma transform, and 64x64 superblocks using the 32x32 luma transform will now use the 32x32 (instead of the 16x16) chroma transform. Lastly, add a trellis optimize function for 32x32 transform blocks. HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's a few negative points here and there that I might want to analyze a little closer. Change-Id: Ibad7c3ddfe1acfc52771dfc27c03e9783e054430

2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
2012-12-0732x32 transform for superblocks.Ronald S. Bultje
This adds Debargha's DCT/DWT hybrid and a regular 32x32 DCT, and adds code all over the place to wrap that in the bitstream/encoder/decoder/RD. Some implementation notes (these probably need careful review): - token range is extended by 1 bit, since the value range out of this transform is [-16384,16383]. - the coefficients coming out of the FDCT are manually scaled back by 1 bit, or else they won't fit in int16_t (they are 17 bits). Because of this, the RD error scoring does not right-shift the MSE score by two (unlike for 4x4/8x8/16x16). - to compensate for this loss in precision, the quantizer is halved also. This is currently a little hacky. - FDCT and IDCT is double-only right now. Needs a fixed-point impl. - There are no default probabilities for the 32x32 transform yet; I'm simply using the 16x16 luma ones. A future commit will add newly generated probabilities for all transforms. - No ADST version. I don't think we'll add one for this level; if an ADST is desired, transform-size selection can scale back to 16x16 or lower, and use an ADST at that level. Additional notes specific to Debargha's DWT/DCT hybrid: - coefficient scale is different for the top/left 16x16 (DCT-over-DWT) block than for the rest (DWT pixel differences) of the block. Therefore, RD error scoring isn't easily scalable between coefficient and pixel domain. Thus, unfortunately, we need to compute the RD distortion in the pixel domain until we figure out how to scale these appropriately. Change-Id: I00386f20f35d7fabb19aba94c8162f8aee64ef2b
